The basic design for kitchen cabinets is a straight line across the longest wall. It's the easiest to build, but isn't the most creative layout. Other popular shapes are the L and the U, but the shape you choose will ultimately depend on the space you have available. Regardless of which design you decide on, it is generally a good idea to plan to have the fridge and stove a fair distance away from each other - the heat from the stove could affect how well your refrigerator works.
